Hi again Carissa,

In my previous email I noted that I made changes (additions) to two
of the GRIB2 tables that 'gribinsert' uses to create valid/complete
LDM/IDD Product IDs.  This process was pretty simple since there
were only two products which were not represented in the tables:

!D# CT# ID# PD# NAME                             UNITS                GNAM      
   SCALE   MISSING
!23|123|123|123|12345678901234567890123456789012|12345678901234567890|123456789012|12345|123456.89|12345678|1234567890
000 006 201 001 SunShine Duration                s                    SUNSD     
       0  -9999.00
002 004 003 000 Unknown NCEP Product             -                    FRWX_3    
       0  -9999.00

The various columns are:

 D#  - discipline (the '!' indicates a comment)
CT#  - category
ID#  - product number
PD#  - product definition template number

The reference I have been using to determine the correct name for GRIB2
parameters is:

NCEP WMO GRIB2 Documentation
http://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc.shtml

Comments:

- This documentation was sufficient for determining that the parameter labeled
  as discipline 0 (Meteorological Products), category 6 (Cloud), parameter 201
  is Sunshine Duration (SUNSD).

- This documentation did _not_, however, provide me with the name for the
  product labeled:

  discipline 2 - Land Surface Products
  category 4   - Fire Weather
  parameter 3  - ??? (the online docs define parameters 0, 1, and 2 only)

Just for testing, I fabricated the name FRWX_3 and added it to the GRIB2
table that 'gribinsert' uses (the entry I fabricated is listed above_.
I would _much_ rather find out what this parameter really is and use
its correct name in LDM/IDD Product IDs.

Questions:

- Can you help find someone who knows what this product really is?

- If you find the right person, can s/he provide a more up to date reference
  for GRIB2 tables than those contained in 'NCEP WMO GRIB2 Documentation'?

Thanks in advance!

Cheers,

Tom
